My problem is I get p0306 and sometimes p0174. The #6 cylinder won't fire. It has good spark, compression and the injector checks ok with opening and holding, ohms, and noid. I was reading a troubleshooting guide on this engine and tried to hook up my laptop and ELM scan tool. I tested spraying some carb cleaner to test the O2 sensors and they seemed to respond. From this picture can you tell me why the STFT No 2 is -1 across the board? Thanks.
